Marv's right about real wrenches, and djshomestead correct toting a belt load of tools. The PlierWrench advantage is an outsized capacity for it's overall length and thickness. Mine hung on the tool wall in Montgomery Ward Hayward or Alameda, CA. And the only thing I could find large enough for a loosened motorcycle fork tube bolt, right at the triple tree.
The spring loaded handle jaw adjustment still surprises me; for not being copied more often.
